,Beit known that I, JAY B. RHoDns, a citizen of the United States, and aresident of Kalamazoo, 4in the county of Kalamazoo and State ofMichigan, have invented certain new and useful Improvements in Dump-Cars, of which the followingis a specication, reference being had to theaccompanying drawingsiy My invention relates to dump cars of thegenera-l type shown and described in my pending application, Serial No.98,1195, tiled May 19, 1916, in which the lateral tilting of the car bedto discharge its load as well as to restore it to its normal position iseilected by power operated pistons or plungers acting through foldingthrust bars, the members of the thrust bars being connected by knucklejoints so that they may swing out of line with each other in onedirection, but not in the other. In the construction shown and describedin my said application the car bed is normally held against tilting bymeans'of certain locking devices comprising chains or other iiexibleconnections connected to the sides of the car bed, and also connectedwith the under body of the car by latch mechanism' which isautomatically released by the actuation of the appropriate bed-tiltingdevices. The ear which forms the subject-matter of the presentapplication employs bed-tilting or rocking devices very similar to thoseof my said application,but instead of employino chain locking devicesfor holding the car be in its normal or horizontal position when in useI emploiT folding struts interposed between the side portions of the carbed and the under body of the car and arranged to ooperate with the. bedrocking mechanism.

so as to permit the bed to be dumped or restored to its normal positionas necessary. 1 am aware that it is not broadly new to employ struts forsupporting the side portions l ot' a dump car bed, but l believe myselfto be the iirst to employ for Jrhat purpose jointed or'folding strutswhich are constructed and arranged so that they fold or collapse 'whenthe appropriate bed rocking mechanism is operated and so permit the carto be dumped, and when the bed is righted are" automa-t1- cally restoredto operative position, and which also remain in operative position vwhenthe car is dumped at the opposite side so that they prevent the bed overbeyond its normal being righted.

1n the accompanying drawings which illustrate one form in'which myinvention may be employed: y

Figure 1 is a side view of the greater part of a dump car;

Fig. 2 is an end view thereof;

Fin". 3 is` an enlarged detail, being a vertical cross-section on line3-3 of Fig. 5;

F ig. 4 is a vertical cross-section of the car substantially on lined- 4of Fig. 1; I

Fig. 5 is an enlarged detail illust-rating the arrangement of one of thesprings which aid in restoring the struts to their normal or operativeposition;

Fig. 6 is ai vertical cross-section on line 6-6 of Fig. 1, the sidegates of the car bed being omitted;

Fig. 7 is an enlarged detail showing one of the thrust bars and one ofthe struts and certain parts connected therewith; and;

Figs. 8 and 9 are similar views showing changed positions of the parts.

eferring to the drawingsindicate-s the car bed which is provided withside gates 11 of any approved construction. 12 indicates longitudinallyextending I beams which form the basis ot the under body of the car frombeing thrown positlon -when it is and are mounted upon trucks 13. 14indicates transversely-disposed bolsters placed at intervals andconnected to the I-beam 12..

Said holsters carry bumpers 15 which limit the extent to which the carbed may tilt. 16 indicates standards arranged at intervals along theunder body on the center line thereof and supporting pivots 17 on w/hp'hthe' car bed is supported by means ot Vdepending lugs 18 securedcentrally to the un der side of the bed as shown in Fig. 1i. 'lyhearrangement is such that the car bed may be tilted to discharge its loadat-either side of the uli-der bodyas is common in dump cars of thistype. 19-20 indicate folding thrust bars at opposite sides of the'lcar.at or near the longitudinal center thereof, said thrust bars beingpivoted at their upper ends to the under side of the 2122 in Fig. 6 sothat they mayv swing laterally in folding. Each of said thrust barscomprises two inembersa-b connected by an offset pivot c so car bed asshown :at i

Each of theinenihers Zi is provided at its lower end with curved linger d d with arecess c as shown in said figure. 23--24f indicate linls which at theirinner ends are niotuutedl lupon one of the pivot pins 17 and at theirouter ends are pivotal-ly connected to the lower ends oi' the inenibersti by Apivots 25-26, respectively. W'hen the members a-b of thethrustbars 19-20 are alined the links S23- 24 serre to hold theni sothat they. assume a dowrm'ardlyw and inwardly inclined position, andwhen the joint of either thrust bnr is broken 'when folding compressedair from any suitable source,

such as a' locomotive or a, compressed air cylinder. The usuel valveniechsnisin is provided so that the compressed sir nier be admitted toor exhausted from either offlinder'et pleasure.- When the compressed airis admitted to either cylinder, as for eXninple the cylinder 3l, itsplunger will be raised soes to carry its plunger rod 27 upward intoengagement with the lower end of the thrust bar 19. To insure properengagement of these parts, the upper end of the plunger rod f' isprovided with a guide link piu oted to it and tothe pin 17, and the.plunger ro'd is arranged to rock lateralli7 unde` the action of saidguide link. Suid plunger is also provided with a rounded head adapted tolit in the recess e the lower end of the thrust bar 19. Thus when theplunger rod 27 is projected by the admission of coinpressed air to thecylinder 3l the head 3l will enter the recess e and apply power to thethrust bar 19 along` a line which falls inside-oi' its piro-t c, andconsequently has Thot side of the car bed will, therefore, be lifted soes to roch it about its pivots 17 and duinp the load at the oppositeside oi. the car., like manner, the plunger rod 28 is provided withguide link 35 which has e heed 36 corresponding to the parts 33 and 34:already described. lVhen the car bed is ltilted so as to discharge atthe right, as' above described, it will be evident that the thrust bar2G will more down with the bed, the lower end et seid thrust bar beingguided by the linlr 2li. At this time the plunger rod 28 occupies theposition shown in Fig. 6, being thenat the lett hand side of its plunger30. 1s the s J; L',

being outside the line of the pirots c and will cause said tnrust tobuckle and tolde thereby permitting that side oii the hed to l descend.in like manner, the phznger rod is proif'ided with e lip 38 whichperforms a similar function when the lood is dumped at the opposite sideot the cer. Froirthe foregoing descriftion it will be apparent that whenthe bed is tilted in either direction from its horizontal position thethrust bar at the high side ot' the lied is not folded and its ineinbersremain in operative relation. to each other, but the. thrust bar at thelow sident the bed is folded inwardly under the bed. ln restoring thebed to its l position7 air admitted to the cj' ft the low causing the ithat side to rise intoengagement wi thrust bar, thei'ebg7 'rocking e bedin the opposite direction until it res ies its horizontal position.. m"t ine retract-ion the plunger rod permits the members of the foldedthrust bar to resume their operation rela-tion ler to irsure this actionl prefer to pro 'ide euch of the thrust bars 19;'20 with a springv 39inounted upon the pivots of' the thrust bois es best shown in Fig. 39ure arranged to act on the nieinbers o or the thrust bars so as to swingtheni outwardly and. bring the members a-ZJ into complete alinernent.

It willbe noted that the shoes e' extend .outward beyond thelines of the pivots 42h4 and 43, respectively, the object of whicharrangement is to cause the struts to break and fold when their lowerends are swung inwardly far enough to carry the line of thrust outsidethe pivots It. 46-47 indicate rook-shafts suitably journaled in thestandards 16 or other suitable supports, and extending 'longitudinallyof the car. Preferably four of these rook shafts are used, two at eachend. 48-49 indicate crank arms carried by the rock shafts 46%7,respectively, adjacent to the end portions of the car, as shown in Fig.4. 50-5l indicate links connecting the cranks 48-49 with the members gof the ,struts 40`41 respectively. It will be apparent that by rockingthe shafts 46-47 the members g may be swung laterally, the shoes z'riding on the rollers 44-45,

v and that thelinks 50-51 also serve to hold the lower ends of thestruts A40-41 in position: Preferably the arm( 49 and link 5l ware 1noii'set relation to the arm 48 and link 50, as indicated in Fig. 4, topermit a wider range of Amovementof the parts. 52 indicates springsmounted on the rock shafts liti-'47, as indicated in Fig. l, which actnormally to hold the arms 48-49 and links 50-51 in the position shown inFig. 4, there by holding the struts 40-41 in operative position. 53indica-tes a crank secured to the vrock shaft 46 and extending over therock shaft 47 adjacent to the link-35 in position to be engaged by aswinging hook 54 pivoted intermediately upon said link, as shown at 55in Fig. 6. 56 indicates a similar crank which is connected to the rockshaft 47 and extends over the rock shaft 46 adjacent to the link 33 inposition to be engaged by a hook 57 pivotally mounted at 58 upon saidlink. lt will be apparent that when the plunger rod 28 is projected todump the car at the left vhand side the link 35 will swing upwardly,carrying with it the hook 54 which will act to swing the crank 53upward, thereby rockingthe rock shaft 46 in a. counterclockwisedirection. link 50 to the right thereby swinging the lower end of thestrut 40 in the same direc- Cnc tlon. As illustrateffl in F ig.l 8, theline of thrust is thus broizght between the toe ot the shoe z' and thepivot 42 so that it is outside of the pivot 7L and consequently thestrut 40 is caused to buckle and fold inwardly as descends, asillustrated in Fig. 9, thus permitting the car to be dumped. As theplunger 28 continues to move upward in the dumping operation, the memberg of the strut 40 is carried over to the right as indicated. in dottedlines in F ig. 9, but when said plunger rod site side of the car is notaiifected This will move the dumping, said l member j g 1s moved backthe shaft 46 effected by the spring 52. Dur- 1ng this operation thestrut 41 at the oppoas the plunger rod 27 remains retracted.. inrestoring the bed to its normal positionafter it-has been dumped in themanner described, air is admitted to the left hand thereby causing itsplunger rod 27 to4 rise and lift the left hand side ofA thebechashasbeen described. During this 'opera-,tion it vis of course necessary thatthe .strut 41- at vthe right hand side of operative position, andconsequently toprevent the projection ofy the plunger rod 27 vfrommoving said strut out of operative position at this time, provision ismade for releasing the hook 57 from engagement with the crank 56 bywhich the rock shaft 47 is rocked. This release is effected by means ofa lug 59 which depends from the car bed in position to engage the upperend57a of theV hook 57 remains in operative engagement with the l crank56 and rocks the shaft 47 for the purpose. described. A similar,v lug 60is provided to coperate with theupper endy 54a of the hook 54. Boththe.' hooks r5 4ya1'1d, 5.7
